Abstract
The utility model relates to a centrifugal fan volute, comprising a circular arc surrounding plate (11), a first flow guiding side plate (12), a second flow guiding side plate, an air outlet surrounding plate (13) and a volute tongue (14), wherein the circular arc surrounding plate (11), the first flow guiding side plate (12), the second flow guiding side plate, the air outlet surrounding plate (13) and the volute tongue (14) form a volute main body. The centrifugal fan volute is characterized in that the end part of the air outlet surrounding plate (13) is inclined towards the inside of an air outlet. Since the structure that the end part of the air outlet surrounding plate of the volute is inclined towards the inside of the air outlet is adopted, the centrifugal fan volute can well rectify the air flow blown from a centrifugal fan, can reduce the speed of air flow blowing from the top so as to lead the air flow to be uniformly distributed on a heat exchanger to take part in heat exchange, and does not generate air flow interference and interference of the high-speed air flow and the heat exchanger, thus eliminating abnormal sound, and promoting heat exchange capability and energy efficiency of the heat exchanger under the same air quantity. The centrifugal fan volute is simple in structure, controllable in technology and lower in cost.
Description
Technical field
The utility model is a kind of centrifugal blower volute, belongs to the improvement technology of centrifugal blower volute.
Background technique
Traditional centrifugal blower volute comprises spiral case circular arc coaming plate 11, the first water conservancy diversion side plate 12, the second water conservancy diversion side plate, exhaust outlet coaming plate 13 and snail tongue 14, five constitute the main body of spiral case, when the centrifugal blower high speed rotating, high velocity air throws away to oblique the place ahead under the effect of centrifugal force and inertial force, wherein a part of kinetic energy is after the spiral case diffusion is dispersed, and the near normal exit end face blows out.
Indoor apparatus of air conditioner is fan coil unit especially, when adopting above-mentioned traditional centrifugal blower volute, because the Velocity Profiles of spiral case outlet is inhomogeneous, the top flow velocity is big, the bottom flow velocity is little, the top high velocity air can produce the high frequency different sound of uttering long and high-pitched sounds during through the micro-gap between vaporizer top fin, fin and the top cover, makes that the tonequality of wind pipe machine is relatively poor; Lower stream of airflow speed is too low, is unfavorable for the vaporizer heat exchange, has influenced the heat exchange efficiency of whole system.The usual method of eliminating the different sound of above-mentioned high frequency at present in the industry is to paste the sound-absorbing material of adequate thickness between centrifugal blower volute outlet section and vaporizer, this method not only increases cost but also process controllability is relatively poor, and because the shield portions exhaust outlet, windage is bigger, influences air quantity.Therefore, be necessary further improvement,, under the prerequisite that does not increase cost, air quantity, eliminate the different sound of this high frequency from the spiral case body.
The model utility content
The purpose of this utility model aims to provide a kind ofly can eliminate the different sound of high frequency, and tonequality is better, and blow even, simple in structure, technology is controlled, lower-cost centrifugal blower volute.
The novel technological scheme of this use is: a kind of centrifugal blower volute, comprise circular arc coaming plate, the first water conservancy diversion side plate, the second water conservancy diversion side plate, exhaust outlet coaming plate and snail tongue, five constitute the main body of spiral case, it is characterized in that the end of described exhaust outlet coaming plate is obliquely installed in exhaust outlet.
The angle α of coaming plate end, described air port and exhaust outlet coaming plate is 0～40 °.
The utility model is because the structure that adopts the end of spiral case exhaust outlet coaming plate to be obliquely installed in exhaust outlet, therefore the air-flow that can well rectification from centrifugal blower, blows out, reduce the top and blow out airspeed, make it to be distributed to uniformly and participate in heat exchange on the heat exchanger, do not interfere and can not produce air-flow interference, high velocity air and heat exchanger, thereby eliminate different sound, promote exchange capability of heat and the efficiency of heat exchanger under identical air quantity.The utility model is simple in structure, technology is controlled, and cost is lower.
Description of drawings
Fig. 1 is the structural representation of prior art centrifugal blower volute.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is applied in structural representation on the air conditioning wind pipe machine for the utility model centrifugal blower volute.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As Fig. 2, shown in Figure 3, the utility model centrifugal blower volute, comprise that circular arc coaming plate 11, the first water conservancy diversion side plate 12, the second water conservancy diversion side plate (not shown), exhaust outlet coaming plate 13 and snail tongue 14, five constitute the main body of spiral case, the end of exhaust outlet coaming plate 13 is obliquely installed in exhaust outlet.The angle α of coaming plate 13 ends, described air port and exhaust outlet coaming plate 13 is 0～40 °.
As shown in Figure 4, be applied in structural representation on the air conditioning wind pipe machine for the utility model.The utility model centrifugal blower volute and place in the spiral case centrifugation blade 2 and provide the motor of power to be fixed on the central diaphragm 3 wherein is with heat exchanger 4, vaporizer sponge 5, top cover 6, vaporizer dunnage 7, water receiving disc 8, vaporizer end plate 9 and the common common air conditioning wind pipe machine that constitutes such as automatically controlled.
In the air conditioning wind pipe machine running, centrifugal blower sucks air from indoor set, blows out behind fan blade.Owing to adopt the end of spiral case exhaust outlet coaming plate in exhaust outlet, to be obliquely installed, therefore, the air-flow that can well rectification from centrifugal blower, blows out, make air-flow evenly blow to each position of heat exchanger and reduce most of air-flow as far as possible and flow to the top cover direction, reduce the mutual interference of air-flow and the interference of high velocity air and heat exchanger, eliminate different sound thereby can reach, optimize tonequality, identical air quantity is realized the purpose of raising ability efficiency down.
Claims (2)
1. centrifugal blower volute, comprise circular arc coaming plate (11), the first water conservancy diversion side plate (12), the second water conservancy diversion side plate, exhaust outlet coaming plate (13) and snail tongue (14), five constitute the main body of spiral case, it is characterized in that the end of described exhaust outlet coaming plate (13) is obliquely installed in exhaust outlet.
2. centrifugal blower volute according to claim 1 is characterized in that the angle α of coaming plate (13) end, described air port and exhaust outlet coaming plate (13) is 0～40 °.
